nrf9160 uart reads one byte at a time

[MosheSmartAmr]

Hi,

I'm trying to receive large packets on uart, but is seems to read one byte at a time . 

uart_fifo_read() always returns 1  

why is that? 

can it be changed ?

why is that?

 Because that's the way it is coded. It indeed always returns one because it always reads one byte at a time.

 

can it be changed ? 

There is an api you can use, found here. There is an example that can read more than one byte at a time, by using DMA.
